WHY IT NEEDS A POLICY

Why index_pdf needs a policy

The description is empty, so classification is based solely on the tool name and server context. 'index_pdf' most likely processes a PDF and writes its content into a search index (a reversible Write operation). It could also involve downloading (triggering an external fetch), but Write is the most probable primary action. Confidence is lowered due to the empty description.

From the tool's definition Tool name 'index_pdf' and server context 'download, index, and semantically search PDF research papers' — the word 'index' implies ingesting and storing/writing data into an index.
